"Men by nature desire to know" Aristotle

"Man, being the servant and interpreter of Nature, can do and understand so much and so much only as he has observed in fact or in thought of the course of nature. Beyond this he neither knows anything nor can do anything." Francis Bacon 1620 "The New Organon"

The claim that greenhouse gases warm up the Earth by 33°C
refers a joint statement by national academies of Brazil, Canada, China,
France, Germany, India, Italy, Japan, Russia, UK and USA in 2005: “the
existence of greenhouse gases in the atmosphere is vital to life on Earth – in
their absence average temperatures would be about 30 centigrade degrees lower
than they are today.”This claim has
been widely endorsed since by numerous academic institutions including the IPCC
around the world.

However, this claim turns out false; it is simply a result
of misuse of the Stefan-Boltzmann law by climate scientists.When deriving this conclusion, climate
scientists made technical errors:

1)treatingthe Earth as a blackbody while it never is;

2)using wrong temperature quantity that is not the
temperature quantity defined by the physics essence of the Stefan-Boltzmann
law;

3)classifying temperatures raised by greenhouse
gases as a different physical quantity outside the Stefan-Boltzmann as well as other related physics laws.

Detailed analysis is summarized in a ppt presentation, which
can be downloaded from this Acribd link:

While studying the IPCC
5th assessment report AR5, the author noted FAQ2.2 Figure 1 that was
used to argue warm days and nights have increased and cold days and nights have
decreased for period 1981-2010 as compared with period 1951-1980.

Firstly, the figure has obviously
misplaced major tick numbers of “10” and “5” for the abscissa; supposedly this is
a simple typo.

Secondly, label for the
ordinate “Probability” does not appear correct.It should be “Probability Density.”Label “Probability” is correct for discrete
probability graphs, which are usually displayed using bar graphs.The graphs in Figure 1 are all in a fashion
of continuous probability
distribution function.Probability for
any interval is expressed by the area size under the probability density curve over
the interval.The X-axis is of temperature
anomaly (°C) instead of the
Z-values, a more precise label for the Y-axis in this case can be “Probability Density
(1/°C)”.

Thirdly, we know logically
that: for discrete probability bar
graphs, summing up all the probability numbers leads to 1; for continuous probability curve graphs, total
area size under the probability density curve must equal 1.

The graphs in FAQ2.2 Figure
1 were digitised, and area size under the graphs was integrated.The area size is found to be an illogical
number approximately 0.5 instead of 1.0.An example with the graph for 1951-1980 daily minimum temperature is
shown in the figure below.This fact
shows that there must be something incorrect in data handling and/or production
of the graphs.
